Invention:
This invention introduces a compact and lightweight system designed to enhance imaging resolution using a metasurface-based spatial mode demultiplexer. It utilizes a specially engineered metasurface that can efficiently sort and detect the first few orders of spatial modes of light, which are then projected onto a high-resolution camera or detector array. By separating these spatial modes, the system improves the resolution of imaging devices, allowing for the capture of fine details that surpass the diffraction limit of traditional imaging systems. The sorted spatial modes' amplitudes are detected and analyzed to reconstruct high-resolution images. It sorts and detects light more efficiently than older, bulkier systems, making it perfect for space imaging and biological research. The compact design makes it easy to use in portable imaging devices, offering better results without the need for complicated, large-scale setups.
Background:
The technology solves the problem of traditional bulky optical systems that are used to improve imaging resolution. Traditional high-resolution imaging methods, such as the SPAtial-mode DEmultiplexing (SPADE) technique, are effective in enhancing resolution but rely on complex, bulky optical setups to separate and detect different spatial modes of light. These setups are impractical for many modern applications, such as space exploration, where there are weight and size constraints, or in biological microscopy, where portability is essential. By using a metasurface, this technology achieves the same high-resolution results but in a much more compact form, making it better suited for space missions and biological studies.
